I have a DC5-R LSD in my TSX. To be honest, it should have come with one from the factory. My only guess is that they left it out and planned on maybe using on a TSX Type-S or something that never came to fruition.
Regardless, best thing you can do for this car. I could go on and on about why and LSD is good, but I won't unless asked. Both of my cars have OEM LSDS
